Zero-click MMS RCE in Samsung Quram Qmage codec
CVE-2020-8899 is a heap-based buffer overflow / buffer overwrite vulnerability in Samsung's proprietary Quram Qmage image codec used in Samsung Android devices. The vulnerable codec is integrated into Samsung's graphics stack via Skia/libhwui and processes QMG/Qmage image content. According to the provided content, malformed Qmage images can trigger memory corruption during image parsing/decoding, including in code paths reached automatically by MMS handling. Project Zero research cited in the content showed that incoming MMS messages could cause Samsung Messages to decode the malicious image before the user opened it, creating a zero-click remote attack surface. The issue affects Samsung Android OS versions 8.x, 9.0, and 10.0, with broader context indicating Samsung devices had carried the Qmage codec since approximately 2014. Samsung tracked the issue as SVE-2020-16747 and patched it in May 2020.
